FREDv C. DE VALLANT, OF .EARLVILLE NEW YORK. I'

To all whom it may concern:

Be itilcnown that I, FRED C. DE VALLAiIT,

a .citizen of the United States, residing 4'at Earlville, in the county of Madison and State of New York, have invented certain new and. useful Improvements in `Pneumatic Dust- Collectors, of whieh'the folles-'ing is a speci- 'fication.

This inventionrelates to pneumatic dust collectors, and pertains especially to a-pneumatic handldevice. for cleaning carpets and {loors The object of the invention is to provide a l suction hand operated machine or device of i' novel and peculiar'construction and arrangef ment. of parts for cleaning carpetsandajloors and adapted to have a. currycomb altfrached thereto for cleaning horses andeattle;

A further object of the invention is to provide a suction apparatus adapted to bev operated by suitable motive power. or by hand,-and having such special construction and relative ,arrangement of parts as to afford simple and expeditious operation.

Various other objects advantages and improved results are attainable in and by the apparatus hereinafter to be fully de- In the accompanying drawings forming partof this application: Figure 1 is a side elevation oflthe apparatus the hosebeing partly broken away, and one side ofthe gear l casing removed. Fig. 2 is a top view without the hose.- Fig. 3 is an enlarged section on the line'a2-, Fig. "2. Fig. L is a sectionalview of av modified form of cylinder cover.

The same reference numerals denote the same parts throughout the several views of the drawings.

The'apparatus or device is mountedon a suitable base-board 1,'whieh may be transported withoutremoving allthe parts therefrom, and preferably none of the parts are removed or detached from .the base, yet they lmay be so attached thereto as to permit removal should occasion demand.

Like others of such machines this machine may be moved from place 'toplace or from one Hoor or` room to another by hand, and while it is shown for hand operation, it

' may be operated f by any suitable lmotive power.

The gears are inc losed by a -easing-.8 having a A y A cylinder 10 forming an air-chamber 11, is supported by a. platform 12 having one end resting on the air-chest 25, and the other end secured'to or seated on a lug 14 of the standard 2. lThe cylinder 1 0 has an vinner annular rim 15 from which is suspended in 'the chamber 11, a dust-bag or sack 16. The

cylinder cover 17 has a flange 18 fitting within the cylinder, andis provided with a conical nozzle 19, having a stem 20, adapted' to be coupled to a hose 21. In'order to make an air-tight joint between the cylinder and itscovei, an elastic or rubber ring or band 22 is placed over the jointA between the cylinder and its cover. This ring or band may be expanded and slid into andout @f posi- .tion on the cylinder in placing and removing the cover without'removing the band. A. horizontal bellows 28 having a dividing partition 24, (making it a double bell lows) is located between the base 1 and the platform '12 and is provided with suitable valves 2G. The air-chest 25 of lthe bellows has suitable valves 27, and is'connected to the base 1 under the platform and in commimication with the air-chamber 1l. "The bellows partition hasv a rod 28 connected with the pinion 3 by a connecting rod 29.;

The hose 21 is connected to a metal hand' pipe having a floor or carpet nozzle-31 attached thereto.

'It is obvious that the machine is capable .of being convenient-ly carried to suchv place.
